A system and method for accelerating file deletion by preloading indirect blocks. When processing level 1 (L1) indirect blocks, the file server issues a read request for the next N indirect blocks to be loaded into a buffer cache. The file server processes the indirect blocks from the buffer cache without requiring multiple single block disk accesses. Once the N indirect blocks have been processed, a read request for the next N L1 indirect blocks is then sent. The technique permits parallel processing by loading indirect blocks to be processed while previously cached indirect blocks are being processed.
